We have used the metrics namely Gross Pitch Error  [1]}, Voicing Decision Error  [1]}, F0 Frame Error  [3]}, Mel Cepstral Distortion  [4]} which are used in audio signal processing to measure the prosody of the signal.All pitch and voicing metrics are computed using the output of the YIN  [5]} pitch tracking algorithm.
For all comparisons of predicted signals to target signals, we extend the shorter signal to the length of the longer signal using a domain-appropriate padding (0 for a time domain waveform and for a log magnitude spectrogram with a \(1*10\textsuperscript {-6}\)  stabilizing offset)
